Experimental study on initial ballistic characteristics of cased telescoped ammunition

Abstract

There is a loading process after the projectile of the cased telescoped ammunition (CTA) fired in the chamber, which has important influence on the stability of interior ballistics, the firing accuracy and the gun barrel life. In order to study the characteristics of velocity and attitude in the initial motion of the projectile of the CTA, a special projectile for the initial ballistic test was designed, and an initial ballistic test system based on the high-speed camera was built. The loading process after firing was observed and the loading velocity was measured. The results show that the loading speed of the projectile is about 30m/s. The initial ballistic parameters of the projectile can be studied quantitatively and the motion attitude of the projectile can be examined qualitatively by using the initial ballistic test system based on the high-speed photography.

Numerical Simulation of Hypervelocity Launch Process of Cased Telescoped Ammunition Armor-piercing Projectile

“…Therefore, it has been widely used in hypervelocity launch in recent years. et al [3] measured the speed of CTA projectile reaching the slope chamber by the high-speed photography device, which is 30 m/s. Zhang H et al [4]- [7] established a model based on the analysis of the characteristics of CTA, numerically simulated the interior ballistic performance of 35 mm CTA gun, and analyzed the influence of gas leakage on it.…”
